Revenue & offtake the regime the project was built under
Offtake regime: Swedish electricity certificate system (elcertifikat)
A built project sells its power under the contract or support regime it was financed with; it is not expected to bid into new government offtake rounds. Where the record does not yet name that regime, the row says so rather than guessing.
Installation how the build is going · from satellite counts and Hafrok’s registers
Satellite survey
the farm as it stands, counted from satellite radar images · built before the count began, so there is no build to chart
Satellite survey
Structures standing23≈48 turbines + 0 platforms expected · 25 fewer than expected — small or closely spaced early turbines fall below the radar threshold or merge into one return
Surveyed2026-09-02≈from 107 satellite passes
Built2007offshore construction to start of operation, from the record
Hafrok counts the structures standing in the sea from satellite radar images (≈) and reads the count against the turbines and platforms on record. The farm was built before this count began, so the images show it complete; they cannot date its construction. Rows marked with a dot (·) come from Hafrok’s own registers.
